.SH DESCRIPTION
This class is defined in the \fBQt Motif Extension\fR, which can be found in the \fCqt/extensions\fR directory. It is not included in the main Qt API.
.PP
The QXtWidget class allows mixing of Xt/Motif and Qt widgets.
.PP
NOTE: This widget comes from the previous Xt/Motif extension. This class is unsupported and has many known problems. It is provided only for projects moving to the new Motif extension. Do not use it new code.
.PP
QXtWidget acts as a bridge between Xt and Qt. For utilizing old Xt widgets, it can be a QWidget based on a Xt widget class. For including Qt widgets in an existing Xt/Motif application, it can be a special Xt widget class that is a QWidget. See the constructors for the different behaviors.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QXtWidget::QXtWidget ( const char * name, Widget parent, bool managed = FALSE )"
Constructs a QXtWidget of the special Xt widget class known as" QWidget" to the resource manager.
.PP
Use this constructor to utilize Qt widgets in an Xt/Motif application. The QXtWidget is a QWidget, so you can create subwidgets, layouts, etc. using Qt functionality.
.PP
The \fIname\fR is the object name passed to the QWidget constructor. The widget's parent is \fIparent\fR.
.PP
If the \fImanaged\fR parameter is TRUE and \fIparent\fR in not null, XtManageChild it used to manage the child.
.SH "QXtWidget::QXtWidget ( const char * name, WidgetClass widget_class, QWidget * parent = 0, ArgList args = 0, Cardinal num_args = 0, bool managed = FALSE )"
Constructs a QXtWidget of the given \fIwidget_class\fR called \fIname\fR.
.PP
Use this constructor to utilize Xt or Motif widgets in a Qt application. The QXtWidget looks and behaves like the Xt class, but can be used like any QWidget.
.PP
Note that Xt requires that the most top level Xt widget is a shell. This means, if \fIparent\fR is a QXtWidget, the \fIwidget_class\fR can be of any kind. If there isn't a parent or the parent is just a normal QWidget, \fIwidget_class\fR should be something like \fCtopLevelShellWidgetClass\fR.
.PP
The arguments, \fIargs\fR, \fInum_args\fR are passed on to XtCreateWidget.
.PP
If the \fImanaged\fR parameter is TRUE and \fIparent\fR in not null, XtManageChild it used to manage the child.
.SH "QXtWidget::~QXtWidget ()"
Destructs the QXtWidget.
.SH "bool QXtWidget::isActiveWindow () const"
Different from QWidget::isActiveWindow()
.SH "void QXtWidget::setActiveWindow ()\fC [virtual]\fR"
Implement a degree of focus handling for Xt widgets.
.PP
Reimplemented from QWidget.
.SH "bool QXtWidget::x11Event ( XEvent * e )\fC [virtual protected]\fR"
Reimplemented to produce the Xt effect of getting focus when the mouse enters the widget. The event is passed in \fIe\fR.
.PP
\fBThis function is under development and is subject to change.\fR
.PP
Reimplemented from QWidget.
.SH "Widget QXtWidget::xtWidget () const"
Returns the Xt widget equivalent for the Qt widget.
